Method for manufacturing an electrode having a metal plate with a recess formed therein, an electrode including the same, and an electrochemical device including the same
The present disclosure relates to an electrode which is manufactured with ease and causes little damage during storage, and a method for manufacturing the same. The electrode includes a metallic current collector and an electrode mixture, wherein the current collector has a recess formed by denting the remaining portions except edge portions having a width, and the electrode mixture is embedded in the recess.
1. A method for manufacturing an electrode for an electrochemical device, comprising:
molding a metallic plate to form a recess in the metallic plate;
embedding a slurry containing an electrode mixture in the recess;
contacting a mold having a pattern formed on a surface thereof to an exposed surface of the embedded slurry to imprint the pattern in the exposed surface;
drying the slurry while the mold is contacting the embedded slurry to form an electrode, the electrode including the electrode mixture embedded in the recess of the metallic plate, and having the pattern imprinted in the exposed surface thereof; and
removing the mold from the electrode,
wherein the recess is defined by four lateral surfaces and a bottom surface, wherein the four lateral surfaces extending from a top surface of the metallic plate, wherein the four lateral surfaces are connected to the bottom surface, and
wherein the dried electrode mixture contacts the bottom surface and the four lateral surfaces thereof, and a height of the dried electrode mixture is the same as a depth of the recess.
2. The method for manufacturing an electrode for an electrochemical device according to claim 1 , wherein the molding comprises:
pressurizing the metallic plate with a press to form the recess.
3. The method for manufacturing an electrode for an electrochemical device according to claim 2 , comprising:
adjusting the pressurizing depth of the press to control a thickness of the electrode.
4. The method according to claim 1 , wherein and at least one of the four lateral surfaces or the bottom surface has at least one convex portion protruding into the recess.
5. The method according to claim 1 , where the imprinted pattern has at least one concave groove.
